Figure 3

Phylogenetic tree (phylogram view) of TrpAa sequences. Nodes occupied by a solid, black circle are supported by bootstrap values of 100%. Other bootstrap values are given within unfilled circles. Xenologs are shown with grey candy-striped bars, and paralogs are shown with lavender/white patterning. A specialized-pathway paralog from Streptomyces coelicolor (Sco_CDA) is shown, as well as a probable specialized-pathway xenolog (Xfa_2) from Xylella [7]. Genes in C. diptheriae, C. glutamicum, and H. pylori that belong to whole-pathway operons originating via LGT are shown within TCG-1. TCG-1 also includes PhnA, encoded by a gene of a partial-pathway operon from P. aeruginosa. TCG-7 is fragmented, the Ban and Sau TrpAa sequences being too divergent to fall within TCG-7.
